As soon as Old Neil finished speaking, the ethereal eyes that had been hovering behind him in the dim light vanished instantly—despite being in a "spirit sight" state, even Klein could no longer detect any trace of their former presence. "This is a hallmark of a ritual magic," Old Neil chuckled. A bit magical... Is spirit sight just an enhanced version of the Yin-Yang eyes? Klein, now like a child excited about a new toy, eagerly shifted his gaze and examined every corner of the room, trying to discern any differences between the current chain-gold chamber and the one he had known before. The dimness outlined the shapes of the objects—tables, beakers, balances, cups, cabinets—all exactly as they had been when Klein first activated his spirit sight, with no hint of radiance. Are inanimate objects truly lifeless? Klein mused quietly, his eyes sweeping over the silver chest resting on the table. Suddenly, he noticed a luminous glow within it—some shimmering like the sky, others brilliant as stars, and others glowing a deep, fiery red! "Materials derived from extraordinary beings possess a certain life—well, vitality—even after the original bearer has passed away?" Kline carefully chose his words, eagerly seeking clarification from the elder Neil. "More precisely, their spiritual essence endures; this is one of the key indicators of successful potion preparation, and also one of the primary causes of extraordinary beings losing control—Dun should have mentioned this to you," the elder explained calmly. Suddenly recalling something, he broke into laughter. "I remember the 'Corpse-Bearer' recipe included dried adult black-spotted frogs. To consume that potion requires a great deal of courage." Kline imagined it and found it somewhat repulsive, neither agreeing nor commenting, instead turning his gaze toward the dim, poorly lit areas around him—hoping to see ethereal beings or ghosts that seemed nearly intangible. "Isn't the spiritual world supposed to be everywhere?" he asked, puzzled. Old Neil cleared his throat and said, "Young fellow, repeat after me:" "This is the headquarters of the Watchers' Team, set deep beneath the earth by the Church of the Night Goddess. Here, there are many extraordinary beings!" "Would we really allow spirits and souls to drift about unattended? And spirits and the concept of spirit are two very different things." Klein felt momentarily embarrassed, turned his head, and pretended to gaze at the faint glow of gas lights near the dark entrance. "I understand," he said. As he spoke, however, his brow began to twitch uncontrollably, as though in spasm. What was going on? Klein was about to turn and ask a question when suddenly, near the inner part of the dark door, at the edge where the bright yellow light shone, he saw a figure nearly transparent, standing still and forming a human shape. Its aura blended perfectly with the dim surroundings, making it nearly indistinguishable. Whoa! Klein's brow suddenly tightened in pain, and his vision grew blurred. When he focused again, there was no trace of that "formless" figure at all! Strange... he turned and said, "Mr. Niel, I'm experiencing a twitching sensation at my brow, and it's a bit painful." "Ah, very normal," smiled Mr. Niel. "As a newly promoted extraordinary, the spiritual vision places significant strain on your 'spiritual body,' continuously consuming your energy. This manifests externally as brow twitching, headaches, heightened sensitivity, and occasional hallucinations. While in the state of spiritual vision, you'll also find yourself uncomfortable in unfamiliar environments and easily influenced by others' emotions—these are all points to pay close attention to. You'll need to adapt and overcome them through consistent practice. Also, be mindful to use it judiciously and know when to exit." How do you feel about this? Mr. Kline asked, eager to learn. He had intended to mention the 'formless' figure he'd just observed, but upon hearing the mention of 'occasional hallucinations,' he decided against it. Given the twitching and stabbing sensation at the forehead, Neil’s explanation was entirely predictable. "Imagine the objects as before, focus and concentrate, then switch into a meditative state, close your eyes, and guide your spirit—repeatedly instructing it to cease. Once you open your eyes again, you’ll notice the spiritual vision has ended." Neil described it leisurely, only adding at the end, "Of course, this is the most cumbersome and clumsy method. Through practice, we can repeatedly suggest to ourselves and influence the spirit during meditation, eventually establishing simple 'on/off' gestures—such as lightly tapping my forehead twice to simply activate the vision, and tapping twice more to easily conclude it. The specific setup depends on your personal habits and preferences." "Understood," said Caine, considering it, and decided to emulate Neil, using a light tap of the forehead twice as the 'on/off' gesture for his spiritual vision. "Once" is easily mistaken for an instinctive head-tapping gesture, while "three times" may waste precious time during a crisis. More individual actions, like snapping fingers, draw attention. He focused his attention, observing the gradually converging spheres of light, and resumed his meditative state. Under Old Neil's guidance, through repeated suggestions and practice, he finally established his "switch gesture." Gently clenching his fist, he tapped the base joint of his index finger twice against his brow, and suddenly, a range of luminous fields—varying in thickness and hue—appeared before him. Tapping twice more, everything returned to normal, with no trace of distinction. "Finally, I've mastered it," he remarked with delight. It wasn't until now that he realized how weary he felt—so tired that he could have fallen asleep at any moment, his mind as if having endured three consecutive nights of sleepless vigil. Old Neil smiled and said, "We are not the 'Never-Sleepers.' Each time you practice excessively or use your spiritual vision too much, you need a period of rest to recover. You can now go home and rest well. In the afternoon, as you walk from Welch's residence toward the Iron Cross Street, make an effort to discover clues about the Antigonus family's notes. We'll continue teaching you about esoteric knowledge tomorrow. Of course, don't forget to read those historical documents." "Very good," Klein enthusiastically agreed with Old Neil's plan. Taking up his walking stick, he stepped out of the Chain-Gold Chamber, watching the dark door close behind him. Old Neil then returned to the weapons store, while Klein rubbed his brow and temples, holding onto the handrail and ascending the stairs one step at a time. At that moment, Dunning Smith approached from behind, his lips slightly curled and his gaze deep and thoughtful. "Old Neil mentioned that you've adapted well—whether it's meditation or spiritual vision," he said. "Perhaps it's just the special nature of a seer." "Klein remained humble in his reply. He suspected that Dune had just been guarding the armory for the old Neil. Dune slowed his pace, only slightly ahead of Klein, and after a moment of silence, without turning around, said: "Remember, curiosity will kill the cat—and also the extraordinary ones. Don't try to hear the whispers you shouldn't, or see the beings you shouldn't." "Understood," Klein knew this was yet another reminder about the extraordinary ones losing control. Upon entering Black Thorns Security, he greeted Rosan, who still seemed unaware of her own extraordinary nature. He then strolled slowly out the main door, onto the street, and took an untracked public horse-drawn carriage back to the street of the Narcissus. On the way, he nearly dozed off. It was still early morning, with the temperature hovering around twenty-six to twenty-seven degrees. Klein reached down from his belt, retrieved the copper key, and opened the door to his own home. Inside the house, many items had not yet been arranged, and both the living room and dining area remained empty. Benson and Melissa, one working and the other reading, had long since left for their respective activities. Without pausing to attend to anything else, Crane closed the door behind him and hurried up the stairs to his own bedroom, a room with a bookshelf. After removing his tailcoat and hanging it on the coat rack, he immediately collapsed onto the bed and fell asleep as soon as his head touched the pillow. — Today is Monday, the day he meets with "The Hangover" and "Justice." Cain thoughtfully tapped his brow twice, and once again, his aura brightened. He tapped it twice more, then stepped out of the spiritual vision, moved easily to the first floor, boiled a pot of water, added a batch of low-grade tea, and with a bit of cream, nibbled on a slice of whole grain bread. Then, Cain pulled out his history textbooks and the original student notes, and began his leisurely review and consolidation. ……… At 2:57 p.m., Cain closed the books, snapped his pen cap, and swiftly drew the curtains shut. Next, he locked the bedroom door, making the room unusually dim. He lightly tapped his brow twice more, activating the spiritual vision and surveying the surroundings. After confirming that there were no intangible spirits present, Cain ended the vision, pulled out his watch, and checked the time. Ticking. Ticking. At three minutes to three, he took four steps backward, just as before, in a counterclockwise motion, forming a perfect square, silently reciting the corresponding incantations in Mandarin with each step. This time, however, he had no main dish prepared. Cain closed his eyes and felt a slight itch on the back of his hand, as if four small black dots forming the square were becoming more prominent, rising to the surface. The wild shrieks and alluring whispers began to echo, but Cain found his headache less severe than it had been the previous time. It wasn't that he was unaffected—he could actively resist the urge to listen. As a "Remarkable One," he had gained a bit more self-control in this environment. Soon, his body lightened, and he floated upward, seeing the diffused, gray-white, boundless, hazy mist, and the countless deep-red "stars" scattered throughout. Among them, two seemed to have a subtle connection to him, evoking a sense of unusual familiarity. Klein gazed at the blurred image of himself, murmured in bewilderment: "The stellar spirit body Neil mentioned?" He composed himself for a few seconds, then once again manifested the grand temple atop the gray mist—the bronze long table situated directly beneath the expansive dome, and the twenty-two high-backed chairs, each bearing symbols of different constellations. Klein quietly walked to the head of the table, settled into the seat, allowing the gray mist to envelop his body and face more fully, and then extended his right hand, pointing remotely at the two familiar "deep red" stars, establishing a remarkable connection.
